This was a great and I must say the best cartoon series ever. The final episode with Superman vs Darkseid with Supes not holding back was great. They show the villains alot which makes for a great series. The episode with Lex Luthor taking over Flash's mind and vice versa was classic. Itwould have been interesting if it was Batman taking over Lex's.
I wish Marvel could make an Avengers cartoon like this with the Master of Evil and Avengers vs Gods arch and even a Cival War cartoon. Here's to wishful thinking.
